Introduction

This analysis implements a comprehensive sentiment analysis of product reviews for the Natural Cassandra Bed with USB Port and Drawers. The analysis includes sentiment analysis, topic modelling, word frequency analysis, and various visualizations to understand customer feedback patterns.

Problem Statement

Analyze customer reviews to understand: - Overall sentiment of reviews (positive, negative, neutral) - Average rating and rating distribution - Geographic distribution of reviews - Key topics and themes in customer feedback - Most frequently used words and their sentiment

Dataset

The analysis is based on customer reviews from Temple & Webster for the Natural Cassandra Bed with USB Port and Drawers.

  • Product: Natural Cassandra Bed with USB Port and Drawers (OIKT2041)
  • Source: Temple & Webster website
  • Analysis Period: Recent customer reviews
  • Variables: Date, Rating, Location, Comment

## 2                                                                                                      These are just what I needed. Easy to make, under bed storage, USB ports for their switch. Easy to move , easy to assemble. Great value.
## 3  This bed frame is absolutely useful and solid, would of been five stars however the usb port has a bright blue light that doesn’t switch off unless no power is supplied so above your head when sleeping you will notice said bright light.
## 4                                                          Love it very much, simple to understand and quicker than predicted to build. However storage rollers are not connected to anything and can be pushed far under the bed accidentally.
## 5                The bed looks amazing. I bought two, one for each of my children, and they love it. They really love the USB port at the bedhead so they can charge their phones overnight. Take a while to put together but worth the effort.
## 6                Very sturdy bed! Love the storage space and colour. Was a little bit complex to set up, and the shelf/headboard is quite low which is a tiny bit disappointing - would’ve preferred it higher and not in line with my pillows.
## 7                                                                                                                                          Very happy with the purchase, easy to put together with plenty of storage space in the bottom draws.
## 8                                                                                                                                                                Fast shipping. Easy to ensemble. Good looking bed frame. My daughter loves it.
## 9                                                                                                                                                                                                            My granddaughter loves her new bed

Step 50: Additional Analysis and Visualizations

Rating Analysis

# Rating distribution
rating_summary <- reviews %>%
  count(rating) %>%
  mutate(percentage = n / sum(n) * 100)

print("Rating Distribution:")
## [1] "Rating Distribution:"
print(rating_summary)
##   rating   n percentage
## 1      4 161  98.170732

# Average rating
avg_rating <- mean(reviews$rating, na.rm = TRUE)
cat("Average Rating:", round(avg_rating, 2), "\n")
## Average Rating: 4.02
# Rating distribution visualization
p_rating <- ggplot(rating_summary, aes(x = factor(rating), y = n, fill = factor(rating))) +
  geom_bar(stat = "identity") +
  geom_text(aes(label = paste0(n, " (", round(percentage, 1), "%)")), 
            vjust = -0.5, size = 4) +
  labs(title = "Rating Distribution",
       x = "Rating", y = "Number of Reviews") +
  theme_minimal() +
  scale_fill_viridis_d() +
  theme(legend.position = "none",
        panel.background = element_rect(fill = "white", color = NA),
        plot.background = element_rect(fill = "white", color = NA))

print(p_rating)

Location Analysis

# Location analysis
location_summary <- reviews %>%
  mutate(state = str_extract(location, "\\b(NSW|VIC|QLD|SA|WA|TAS|NT|ACT)\\b")) %>%
  filter(!is.na(state) & state != "") %>%

# Location visualization

  geom_bar(stat = "identity") +
  geom_text(aes(label = n), hjust = -0.5, size = 4) +
  labs(title = "Reviews by State",
       x = "State", y = "Number of Reviews") +
  theme_minimal() +
  coord_flip() +

        panel.background = element_rect(fill = "white", color = NA),
        plot.background = element_rect(fill = "white", color = NA))

print(p_location)

Statistical Analysis

# Correlation between rating and sentiment
rating_sentiment_corr <- cor(reviews$rating, sentiment_results$sentiment_score, use = "complete.obs")
cat("Correlation between rating and sentiment score:", round(rating_sentiment_corr, 3), "\n")
## Correlation between rating and sentiment score: -0.124
# Sentiment by rating
sentiment_by_rating <- sentiment_results %>%
  group_by(rating, sentiment_label) %>%
  count() %>%
  pivot_wider(names_from = sentiment_label, values_from = n, values_fill = 0) %>%
  mutate(total = positive + negative + neutral) %>%
  mutate(positive_pct = positive / total * 100,
         negative_pct = negative / total * 100,
         neutral_pct = neutral / total * 100)

print("Sentiment by Rating:")
## [1] "Sentiment by Rating:"
print(sentiment_by_rating)
